IGNITER.

Specification of Letters Patent.

Application led January 28, 1910. Serial No. 540,534.

To all whom it may concern:

Be it known that I, ALBERT DE RosE, a citizen of the United States, anda resident of Gilroy, in the county of Santa Clara and State ofCalifornia, have invented a new and Improved Igniter, of which thefollowing is a full, clear, and exact description.

My invention relates to igniters, more particularly to that type ofigniter adapted to ignite explosive liquids and the like.

My invention is especially adapted for use in igniting explosive liquidssecreted in holes and burrows made and inhabited by gophers and thelike.' The gopher yearly creates great damage to valuable crops andtrees, and various means have been tried to rid a territory of thisburr-owing pest. One of the successful methods of exterminating gophersis to secrete an explosive liquid, such as carbon bisulid, in the holeinhabited by the gopher, and explode the same by ignition. Seriousaccidents sometimes result and large pastures are often burned, due tothe fact that the liquid to be exploded is ignited on the surface of theground. For this reason I have invented an igniter adapted to be loweredinto the gopher hole or t-he like, in close proximity to the explosiveliquid and ignited by the operator standing outside and away from thehole.

Reference is to be had to thc accompanying drawings forming a part ofthis specification, in which similar characters of reference denotecorresponding parts in all the views. and in which- Figure 1 is a sideelevation showing a gopher hole and my igniter inserted therein; Fig. 2is a sectional side view of my igniter; and Fig. 3 is a sectional viewtaken on the line 3-3 in Fig. 2, looking in the direction of the arrow.

In a gopher hole 10 is deposited an ex plosive liquid 11, preferablycarbon bisuliid, ready to be ignited by an igniter 12. The igniter 12comprises a tube 13 having an outwardly diverging opening 14 at thelower' end and provided with a cap 15, screwthreadedly secured to thetube 13, and having therein a hole 16. Securely fastened to the tube 13by a rivet 17 is a suitable spring 18. Directly opposite the spring 18are numerous corrugations 19 extending horizontally of the tube 13, soas to form a convenient igniting surface. Slidably held in the tube 13is a rod 20, comprising a suitable handle 21 and a cap 22 provided withan opening 23 adapted to receive a match 24. A suitable screw '25 forrigidly holding the match 24 is provided on the under side of the cap22.

The operation of my device is as follows: A combustible liquid, such. ascarbon bisulfid, is deposited in the gopher hole or the like, as isshown in Fig. 1. An ordinary parlor -match is then fastened to the rod20 by means of the screw 25 and the igniter is then inserted into thehole in close proximity to the combustible liquid. Then by moving therod 2O upwardly and downwardly by means of the handle 21, the ignitibleend of the match 24 engages the corrugations 19 in the tube 13. Thefriction caused by this movement of the rod ignites the match which inturn ignites the combustible liquid.

I do not limit myself to the shape of the tube used on the igniter, itbeing understood that square, oval, round or triangular tubing can beused, depending entirely upon the existing conditions.

It will be further understood that by removing the upper cap 15, theigniting rod can be withdrawn from the tube so as to clean the same orreplace the same with a new igniting rod, and that the igniting rod canbe adapted to fit inside either' a. round, square, oval or triangulartube.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

An igniter, comprising a tube having an open end and a closed end;corrugations on the inner periphery of the tube; `a spring opposite thecorrugations; an igniting rod mounted to slide in the tube and engagedby the spring; a cap on one end of the iguiting rod and integraltherewith; and a set screw adapted to secure igniting means and screwthreadedly engaging the cap.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

ALBERT DE ROSE.
